There are several ways to achieve it. The first and best and cheapest is to pop the battery negative lead off and press the brake pedal. This does a "soft reset" of the ECU and one of the things reset is the fuel map.

There are other things reset by this process: the trip meter (not the odometer) and the radio's PIN acceptance - you'll need that. It might also reset the auto-up on the driver's window and the anti-hijack feature with the keyfob remote unlock.

A couple of seconds should be plenty, it is just to help remove any residual charge from the capacitors in the ecu.
